## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability stablephone-numbers-44f7a58c
```

Example prompt: Show me all the phone numbers I have on my StablePhone wallet.

## When to prefer this

Use this endpoint when you need to know which phone numbers are currently associated with the authenticated wallet before making a call or setting a caller ID. It is the canonical way to list owned numbers on StablePhone and should be called before operations that require selecting a number.

## Known failure modes

- Missing or invalid SIWX authentication returns unauthorized error
- Wallet has no associated phone numbers returns empty array (not an error)
- Expired SIWX token causes authentication failure

## How this service works

List phone numbers for the authenticated wallet. Requires SIWX.

## Output

Returns a list of phone numbers owned by the authenticated wallet and a success boolean. If none are owned, returns an empty array with success:true.

## Example request

```json

```
